At what point do you need to replace stock manifold?

I'm running a stock Cobra intake manifold on a 1998 Cobra.
Anyone know max HP its good for before its time to replace it with an aftermarket?

thanks

From what I hear the TB and Intake can pretty much take anything you can throw at it as far as N/A goes. However, with that being said, if you decide to go F/I, then yeah, changing it will be better for the engine.

Guys, please correct me if I'm wrong.
